I think a few widgets realted to data usage would be nice.

1 - Pool data used /left

I think a widget that would show how much data as been comsume in the company pool would be nice. (extracted from the telecom expanse feature).

Let's say I have 100 users each with a 3Gb data plan.
A simple graph showing how much as been used and being able to but a certain % for yellow (warning) and a % red for alert would be nice.

2 A graph showing how many user are bellow the warning limit of their dataplan.

Again related to the telecom expense. Let's say I have 100 users with 3Gb data plans. I configure a warning at 2.5G and 10 users are over the 2.5 (warning) and 5 users are overs de 3Gb (red).
